To all whom it may concern.-

Be it known thatI, KNIGHT W. GALE, a citizen of the United States,residing at Los Angeles, in the count-y of Los Angeles and State ofCalifornia, have `invented a new and useful Improvement inDoor-Closures, of which the following is a specification.

An object ofthis invention is to provide simple, inexpensive andreadily-applied means whereby a door may be so constructed that when thedoor is closed it entirely closes the doorway, and immediately upon theopening movement of the door clearance is given whereby the door mayswing over thick rugs upon the floor without interference. s

The accompanying drawings illustrate the invention.

Figure l is a fragmental elevation showing a door-closure embodying thisinvention as the same appears when Vthe door is closed. Portions arebroken away to eX- pose parts that would otherwise be hidden. Fig. Qisan enlarged sectional Vdetail showing the position of parts when thedoor is open. Fig. 3 is a plan section on line m3, Fig. 2, parts beingbroken away to expose features of construction. Dotted lines indicateposition of partswhenthe door is closed. Fig. 4 is a plan of thebracket-bar. Dotted lines indicate parts below. the same. Fig. 5 is aplan of the bracket detached. Fig. 6 is a fragmental view of the freeedge of the door open. Fig. 7 is a like view of the free edge of thedoor closed. Fig. 8 is a fragmental view of the hinged edge of the dooropen. Fig. 9 is a fragmental view of the hinged edge of the door closed.Fig. 10 is a section on line m10, Fig. 1.

1 designates a door-frame ofusual construction.

2 designates a door hinged to the frame in the usual manner.

3 designates a groove in the bottom of the door. 4 isa strip in saidgroove, the ends of the same being approximately of the same dimensionsas the groove so as to be adapted to snugly lit in and closethe grooveat the edges of the door. The intermediate portion of the strip is outaway to receive the operating mechanism.

5 designates a bracket in the groove secured to the door by screws 6 andadapted to form a socket or seat to hold a bracket-bar 7 that is fittedat one end 8 to engage in the seat s of the bracket 5 and to besupported thereby, and provided at the other end with a yperforated arm9 let into the edge of the doorl and fastened thereto yby suitablefastening meansas. a screw 10.

llvdesign-ates a slide attached to and longitudinally. movable on theunder side of the bracket-bar 7.

12 is a spring connected with the slide to normally 'projectone end 13of the slide out ward ,beyond the arm 9 and the hinged edge of the door.Said end 13 is deflected away from the axis a upon which the door ishinged. The inner end of the slide is provided with a head 14. f

l--designates a hanger projecting downwardly from the bracket-bar 7 tosupport a bell-crank-lever 16 that is pivoted thereto and that has onearm in operative engagement with vthe head 14 of the slide so that thelongitudinal movement of the slide will rock the lever on-its pivot 17.The longer arm 18 of thelever is pivoted to a screwthreaded post 19which is screwed into the strip 4 at the middle thereof.

When the door is open, the spring V12 draws the slide toward the hingededge of the door, thus to raise the longer arm-of the lever, therebyto.l draw the strip up into the door.y This also causes thedelected endof theslide to proj ect toward the door-j amb 1. As the door is closedthe finalv movement thereof brings the projected end of the slideagainst the door-jamb, thereby forcing the slide into the door andforcing downward the long end of the lever whereby the strip is forceddown into contact with the floor or floor-covering, from whence it willbe withdrawn by the force of the spring 12 when the door opens. Byreason of the deflection or bend at the end of the slide the sameengages the door-jamb in an effective manner to quickly force down thestrip whenever the door is fully closed. The parts may be so constructedand proportioned that as the door is opened the slide becomes releasedand the strip fully retracted into the door before the free edge ,of thedoor is swung free from the door-frame, thus allowing thick rugs to bebrought close to the closed door without liability of interfering withthe movements of the'door.

The slide may be connected with the lever by any suitable co-ntrivance.In thefdrawings the slide is shown provided in its head 14 with a seatin the form of a hole 20 through which the short arm of the leverprojects, and by which it is actuated.YH The slide is also provided withslots 21, 22, one for a fastening screw 23 that is passed there-Ythrough and screwed into the bracket-bar 7 and the other for a stud 24Cfastened to the bracket-bar and extending throughl such other slot tohold one end of the `spring 12, the other end of which isV fastened to astud 25 on the slide 11. l

In practice, to operate the slide, the bracket-bar, slide, lever, springand pivot-post may be attached together to form a xture to be soldtogether with the bracket 5; while the strip 4 and the door willpreferably be supplied by the mill. Or, doors already manufactured andeven after the same are installed may be separately grooved and a slideprovided therefor by any carpenter, so that the attachments may beapplied to the door at any time.

VTo assemble the parts in the grooved door the bracket 5 will first beinserted into the groove and secured there by screws 6. Then thepivot-post will be screwed into the top of the weather-strip at themiddle thereof, and then the strip and fixture may be inserted into the'roove. This may be done before the door is hinged in place or while thedoor stands ajar. The groove is located centrally of the door betweenthe sides thereof, and is sufficiently narrow to be exposed when thedoor is ajar; consequently the strip may be readily removed by beingwithdrawn from the edge of the door when-l ever the screw 10 isunscrewed for that purpose.

26 designates a rub plate which may be simply a smooth-headed naildriven into the door-jamb to receive the wear of the end of the slide13.

YI claim 1.v A door provided. in the bottom thereof with a groove and aseat, a bracket-bar havingone end in said seat and the other endfastened to the edge of the door, a slide carried by and longitudinallymovable on the lbracketfbar, a spring to normally hold theslideretracted to project an end of the slide 'to engage the do'or-jamb,a bell-crank-lever pivoted to the bracket-bar and operatively engaged bythe slide, a strip vertically movable in the groove, and a screw-postpivoted to the lever and screwed into the strip.

2. A door provided in its bottom with a lever and adapted to be therebydrawn into the groove in the door and adapted to be moved by the leverto project from the groove, and a spring to hold the slidein position toretract the strip with one end of the slide projecting beyond the edgeof the door, and adapted to slide into the door for the purposeofprojecting the strip from the groove.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 7th day of April 1908.
